Nickel vanadate nitrogen-doped carbon nanocomposites for high-performance supercapacitor electrode
A nickel-vanadium-based bimetallic precursor was produced using the polymerization process by urea-formaldehyde copolymers. The precursor was then calcined at 800 °C in an argon ambiance to form a Ni(3)V(2)O(8)-NC magnetic nanocomposite. Powerful techniques were used to study the physical characteri...

description | A nickel-vanadium-based bimetallic precursor was produced using the polymerization process by urea-formaldehyde copolymers. The precursor was then calcined at 800 °C in an argon ambiance to form a Ni(3)V(2)O(8)-NC magnetic nanocomposite. Powerful techniques were used to study the physical characteristics and chemical composition of the fabricated Ni(3)V(2)O(8)-NC electrode. PXRD, Raman, and FTIR analyses proved that the crystal structure of Ni(3)V(2)O(8)-NC included N-doped graphitic carbon. FESEM and TEM analyses imaging showed the distribution of the Ni(3)V(2)O(8) nanoparticles on the layered graphitic carbon structure. TEM images showed the prepared sample has a particle size of around 10–15 nm with an enhanced active site area of 146 m(2)/g, as demonstrated by BET analysis. Ni(3)V(2)O(8)-NC nanocomposite exhibits magnetic behaviors and a magnetization saturation value of 35.99 emu/g. The electrochemical (EC) studies of the synthesized Ni(3)V(2)O(8)-NC electrode proceeded in an EC workstation of three-electrode. In a 5 M potassium hydroxide as an electrolyte, the cyclic voltmeter exhibited an enhanced capacitance (C(S)) of 915 F/g at 50 mV/s. Galvanic charge-discharge (GCD) study also exhibited a superior capacitive improvement of 1045 F/g at a current density (I(t)) of 10 A/g. Moreover, the fabricated Ni(3)V(2)O(8)-NC nanocomposite displays a good power density (P(t)) of 356.67 W/kg, improved ion accessibility, and substantial charge storage. At the high energy density (E(t)) of 67.34 W h/kg, the obtained P(t) was 285.17 W/kg. The enhanced GCD rate, cycle stability, and E(t) of the Ni(3)V(2)O(8)-NC magnetic nanocomposite nominate the sample as an excellent supercapacitor electrode. This study paves the way for developing effective, efficient, affordable, and ecologically friendly electrode materials. |
